As expected, Jay Z's Magna Carta . . . Holy Grail holds at No. 1 for a second week on the Billboard 200, selling 129,000 copies, according to Nielsen SoundScan (down 76%). The set debuted atop the list last week with 528,000.

As the set retains the No. 1 crown, it's the first rap album in nearly two years to spend two weeks at No. 1. The last rap album to rack up two weeks in the penthouse was Lil Wayne's Tha Carter IV, which led the Billboard 200 on the charts dated Sept. 17 and Sept. 24, 2011.

Following Bareilles is the latest Kidz Bop album, Kidz Bop 24, entering at No. 3 with 62,000. The popular series—which mostly consists of child-friendly covers of hit songs—has now logged 17 top 10 albums. A No. 1 title still eludes the franchise, which launched in 2001 with the first Kidz Bop album. All of the numbered "Kidz Bop" titles—except for volumes 1-6 and 17—have debuted in the top 10.

Next up, rapper Ace Hood secures his best sales week and highest-charting album, as Trials & Tribulations bows at No. 4 with 34,000. His previous best week was logged with his last entry, 2011's Blood Sweat + Tears, which debuted and peaked at No. 8 with 26,000.

The Teen Beach Movie soundtrack surfs in with a debut at No. 8 with 25,000, following the much-watched premiere of its companion Disney Channel film. According to Disney Channel, the movie's bow on July 19 earned 8.4 million total viewers, making it the most-watched TV movie this year.

Teen Beach Movie is the first non-sequel TV movie soundtrack to debut in the top 10 on the Billboard 200 since the chart dated July 5, 2008. That week, Disney Channel's first Camp Rock soundtrack bowed at No. 3.

Rounding out the top 10 are Justin Timberlake's The 20/20 Experience, which climbs 13-9 with 24,000 (up 33%) and the arriving Cody Simpson, at No. 10. The latter scores his best sales week yet, as Surfers Paradise splashes in with slightly more than 24,000. The set—his second full-length album—is also his highest-charting release.

Simpson's previous high-water mark—both in terms of sales and position—was reached with his first chart entry, 2011's Coast to Coast EP. It debuted and peaked at No. 12 with nearly 24,000. The following year, his debut full-length set, Paradise, reached No. 27 in its premiere frame (15,000).

Over on the Hot Digital Songs chart, there is little movement in the top 10. So little movement, that only four songs shift places—barely. No. 1 again is Robin Thicke's "Blurred Lines," featuring T.I. & Pharrell. The smash single sells another 340,000 downloads, down by 11% for the week. Its total sales now stand at 3.6 million.

Florida Georgia Line's "Cruise" stays its course at No. 5 with 138,000 (down 13%), Daft Punk's "Get Lucky," featuring Pharrell Williams, is also a non-mover at No. 6 with 132,000 (down 16%). Anna Kendrick's "Cups," from "Pitch Perfect," rises a position to No. 7 with 122,000, the only sales gain in the top 10. (The song is up by 1%.)

This is the first week since the Feb. 16 chart where the No. 10 title sold fewer than 100,000 copies.

Overall album sales in this past chart week (ending July 21) totaled 4.7 million units, down 6% compared with the sum last week (5 million) and down 12% compared with the comparable sales week of 2012 (5.4 million). Year-to-date album sales stand at 156.5 million, down 6% compared with the same total at this point last year (167.2 million).

Digital track sales this past week totaled 22.84 million downloads, up less than 1% compared with last week (22.78 million) and down 7% stacked next to the comparable week of 2012 (24.5 million). Year-to-date track sales are at 752.2 million, down 3% compared with the same total at this point last year (773.5 million).

Next week's Billboard 200 competes with the same week in 2012 when: Zac Brown Band's Uncaged returned to No. 1 for a second week, selling a mere 48,000 (down 38%). The top debut was Gaslight Anthem's Handwritten, which started at No. 3 with 40,000.
